From which bacteria thermo stable taq DNA polymerase is isolated ?

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the specific bacteria from which the thermostable Taq DNA polymerase is isolated.

2. **Identifying the Enzyme**: Taq DNA polymerase is a type of enzyme that is crucial for the Polymerase Chain Reaction (PCR) technique, which is used to amplify DNA.

3. **Source of Taq DNA Polymerase**: Taq DNA polymerase is derived from a thermophilic bacterium, meaning it thrives at high temperatures.

4. **Naming the Bacterium**: The specific bacterium from which Taq DNA polymerase is isolated is *Thermus aquaticus*.

5. **Functionality of Taq DNA Polymerase**: This enzyme is thermostable, allowing it to function at the high temperatures required during the PCR process, which is essential for denaturing DNA strands.

6. **Production of the Enzyme**: Although Taq polymerase is isolated from *Thermus aquaticus*, it is often produced and expressed in *Escherichia coli* for practical applications.

**Final Answer**: Taq DNA polymerase is isolated from the bacterium *Thermus aquaticus*.
